Insulated Double Z

100%!!! Don’t over inflate. And the Big Agnes Double Z is amazing. That’s what I use. It’s so worth the extra weight.

Big Agnes has been great here (most comfortable I have ever used). Though I have their old double version.

Really? I get the best sleep of my life when backpacking and sleeping on my inflatable sleeping pad I bought like a decade ago. It’s the Big Agnes Double Z, they don’t make it anymore but it feels like sleeping on an air mattress because it’s so big and fluffy. The key I’ve found is getting the right inflation level, which is much less than I initially thought I would want.

Dang maybe I really lucked out with my initial pick. My Big Agnes pad is the only inflatable one I’ve owned since switching from a cheap roll-up foam pad. I’m seeing a lot of the same positive stuff about their pads in this thread.

Be wary of uninsulated air mattresses in mild temps.  I bought 2x Big Agnes insulated pads for my twins, along with the BA kid’s sleeping bags for our twins. This is more of a backpacking setup, but works great for car camping and living room camping.  The bags have a sleeve on the bottom so you can slide the pad inside. Helps keep them in the bag and on the pad - again - cause the cold ground can give them a chill. 

I’ve got 2 BA pads for my kids but haven’t had any issues with them at all, but they don’t seem anywhere as nice as my Nemo Tensors. A buddy has an BA pad and did get it replaced via warranty.  With that said, my Nemo Tensors have been amazing and one of them lasted over 7 years. Got it replaced very easily with Nemo, too!

The only pillow i've ever found comfortable was the REI Co-Op Trailmade pillow. It's a non-inflatable pillow stuffed with memory foam squares. So it's definitely heavier and takes up more span than inflatable pillows, but after trying several brands of inflatable I just needed something different. I don't see it for sale anymore, so not sure if they still make it. If you aren't hiking in, and size isn't an issue, I would just use your home pillow. For me the big thing for side sleeping/stomach sleeping is a good mattress. If space isn't an issue a foam mattress would be best, there are a bunch of \~$50 tri-fold 4" memory foam mattresses on amazon. But these take up a HUGE amount of space in a car to transport. For backpacking I use an inflatable Big Agnes insulated pad, but those are like $150. If you aren't backpacking, amazon has several options for cheap inflatable camping mattresses, but you will probably need to buy or borrow an air pump to fill them, as they don't come with them usually. For the sleeping bag I've found I can sleep in any style as a stomach sleeper. Mummy style bags just kind of stay with you, so when you curl your legs up, the bang stays mostly form fitted. If you are sleeping on your stomach, do you sleep in "tiger pose" where you have one leg bent up and the other straight? Mummy bags can make sleeping like that difficult. Big rectangle bags would let you sleep in "tiger pose" with one knee up and the other leg straight, which is how I sleep at home. If you are going with a non-down warm sleeping bag, you can always bring a secondary blanket too, so you don't have to splurge on a super expensive 20 degree bag or anything.

Big agnes for the win. I had two of their insulated inflatables, and they were the best 2 pads I ever had. But got holes I could not locate despite weeks of trying. I'm ready to get another, even if it only lasts a couple seasons

Big Agnes pads are some of the toughest out there as far as I can know, yet I have gone through three because of punctures. Each time the holes have been so small that I can't find them without getting to a hotel and submerging them in the tub. The company is great about replacing them, but I've gone back to foam mats.
